On a 32 bits system, it can crash if the scene demand more than 4 Gb.
Not a POV-Ray limit, but a system whide limitation.
On a 64 bits system, the actual limit is MUCH MUCH larger at more than
16 PETA bytes... Or as much RAM plus any swap/page file you can manage
to get.

It seems povray crashes if the memory use gets larger than physical and virtual
ram.

Question - what's the process for getting hold of the povray source files? Are
they available online somewhere? Do I contact the author?
Thanks,
Max

It won't crash, but it will choke nonetheless, in that it will enter
swap hell. And on some operating systems, it will drag the whole OS with it.

Just visit the public repository on GitHub:
https://github.com/POV-Ray/povray

Don't do that then.

I must be blind - can you point me explicitly to the samples?
I see the samples in distribution/scenes/ and have looked through them, but I do
not see these hall of fame items.
Is there a public samples repository?
Thanks,
Max

I thought you meant the PovRay source code.
For the SDL scenes you will need to contact the author.
You might find that some of them have posted their scenes on their web
pages.

Sorry, misunderstanding - I thought you meant the source code of the
POV-Ray software.
I've now come to the conclusion that you really meant the POV-Ray
_scene_ files [for the POV-Ray hall-of-fame images mentioned earlier].

It's not a hard crash, it's a fatal error condition that forces POV-Ray
to abort it's current operation.
